Review on 🐶 NBJU Rechargeable Bark Collar for Dogs - Adjustable Sensitivity & Intensity, Anti-Barking Training Collar for Small, Medium, and Large Dogs (Black) by Heather Wilkinson

Didn't work on our determined barking dog. It was difficult to change the settings, the collar was difficult to adjust to fit properly on the dog, and it still fastened with a cheap plastic clasp (the buckle is easier to tighten). Even though we shaved her neck and set all the settings to 7 (which is hard to understand) she kept barking and seemed to stop working after 2 or 3 days. Put a dr Trainer Pro Bark on her (about $10 more than this) and she reduced barking by about 80% and our other barking dogs stopped using the Dr Trainer entirely. He has a bark monitoring app already set up and ready to go. I have 6 types of collars, from cheap Chinese ones for $30 to $110 for sporting dogs. dr Trainer is the best I've found for $43. This one I thought might be close but was completely disappointed. I sent it back for a refund.
